New cases of chronic wasting disease found in wild deer

Hunters continue to play important role in disease surveillance

Edmonton... Twelve new cases of chronic wasting disease have been identified in wild deer as a result of Alberta’s fall surveillance program. Hunters have submitted more than 4,800 wild deer heads for testing since September 1, 2009.

One new case was detected south of Highway 1, 25 kilometres south of Medicine Hat. Another case was found just east of Highway 884 along the Red Deer River. These cases mark the furthest south and west locations where chronic wasting disease has been detected. The remaining 10 cases were detected near past positive cases. Eleven of the 12 new positive cases were mule deer and nine of the hunter-killed cases were adult males, including an adult male white-tailed deer. The chronic wasting disease hunter surveillance program for 2009-2010 cost $500,000.

Sustainable Resource Development continues to talk with stakeholders and landowners in the area to discuss plans for management. Current strategies for monitoring the spread of chronic wasting disease include maximizing the harvest of deer in risk areas and continuing to test for the disease. This includes testing road-kill and any wild deer that may show symptoms of chronic wasting disease, which includes loss of coordination, weight loss, excessive salivating and isolation from other deer.

The 12 new cases, along with an emaciated deer found in June, bring the total to 13 new cases of chronic wasting disease found in 2009. Since the first case of chronic wasting disease was detected in 2005, there have been 74 cases of the disease detected in wild deer in the province. Ongoing surveillance of wild deer and elk in Alberta began in 1996. There is no scientific evidence to suggest that chronic wasting disease can affect humans.

Alta. finds CWD cases roaming south, west

While Alberta's fall surveillance program for chronic wasting disease (CWD) in wild deer has turned up fewer cases than last year's, deer with the disease were found further south and west than previously detected.

Hunters have submitted more than 4,800 wild deer heads for testing since Sept. 1, 2009, the province said in a release Friday. Of the 12 new cases of CWD identified, 10 were detected near past positive cases.

One new case, however, was detected south of Highway 1, 25 kilometres south of Medicine Hat. Another case was found just east of Highway 884 along the Red Deer River.

The 12 new cases, along with an "emaciated" deer found in June, bring the total to 13 new cases of CWD found in 2009, down from 25 in 2008. Since the first case of CWD was found in the province in 2005, there have been 74 cases in Alberta's wild deer.

Eleven of the 12 new positive cases from the fall program were mule deer and nine of the hunter-killed cases were adult males, including an adult male white-tailed deer, the province said.

Current strategies for monitoring the spread of CWD include "maximizing the harvest" of deer in risk areas and continuing the testing program. The province has run ongoing surveillance in elk and wild deer since 1996.

The province's surveillance program includes testing roadkill and any wild deer that may show CWD symptoms, such as loss of co-ordination, weight loss, excessive salivating and isolation from other deer.

The province's sustainable resource development ministry said it "continues to talk with stakeholders and landowners in the area to discuss plans for management."

According to Saskatchewan's environment ministry, CWD was unintentionally introduced into farmed elk population taken from South Dakota and has since been introduced to Saskatchewan, Alberta and Korea. The economics of trade in live elk and their products, such as antler velvet, has been affected as a result.

Because CWD belongs to the group of transmissible spongiform encephalopathy (TSE) diseases along with BSE in cattle, scrapie in sheep and Creutzfeldt-Jakob disease in humans, the association has led to possible public health concerns -- although there remains no scientific evidence that CWD can infect humans.

The disease can be transmitted from one animal to another, mainly through contaminated saliva or contaminated feed and water. Infectious material can survive in the environment for an unknown period -- at least three years, the Saskatchewan government said.

CWD has also been found in three isolated geographic areas of Saskatchewan's northeast, northwest and southwest.

Abstract

Substantial evidence for prion transmission via blood transfusion exists for many TSE diseases. Determining which cell phenotype(s) are responsible for trafficking infectivity has important implications in understanding dissemination of prions as well as their detection and elimination from blood products. We used bioassay studies in the native white-tailed deer and transgenic cervidized mice to determine: (a) if chronic wasting disease (CWD) blood infectivity is associated with the cellular vs. the cell-free/plasma fraction of blood, and (b) in particular if B cell (MAb2-104+), platelet (CD41/61+) or CD14+ monocyte blood cell phenotypes harbor infectious prions. All four deer transfused with the blood mononuclear cell fraction from CWD+ donor deer became PrPCWD-positive by 19 months post inoculation, whereas none of the deer (0/4) inoculated with the same source cell-free plasma developed prion infection. All deer (4/4) injected with B cells, and 3/4 deer receiving platelets from CWD+ donor deer became PrPCWD-positive in as little as 6 months post inoculation, whereas none (0/4) deer receiving blood CD14+ monocytes developed evidence of CWD infection (immunohistochemistry and western blot analysis) after 19 months of observation. Results of the Tg(cerPrP)mouse bioassays mirrored those in the native cervid host. These results indicate that CWD blood infectivity is cell-associated and suggest a significant role for B cells and platelets in trafficking CWD infectivity in vivo and support earlier tissue-based studies associating putative follicular B cells with PrPCWD. Localization of CWD infectivity with leukocyte subpopulations may aid in enhancing sensitivity of blood-based diagnostic assays for CWD and other TSEs.

175 DEER TEST POSITIVE FOR CWD IN WISCONSIN

CWD Update: Disease Prevalence Rates Continue to Rise
News Release Published: March 15, 2010 by the South Central Region

Contact(s): Davin Lopez, CWD Project Leader, Madison: (608) 267-2948

MADISON – The Department of Natural Resources sampled and tested more than 7,100 deer during 2009 in the Chronic Wasting Disease-Management Zone (CWD-MZ), with 175 testing positive for CWD, the state agency announced today.

Test results for 2009 in the 210 square mile Western Core Area, which mainly encompasses western Dane and eastern Iowa counties, show that the overall trend in the prevalence rate – the percentage of deer testing positive for CWD – continues to increase. The Western Core Area has the highest prevalence rates in Wisconsin.

Since 2002 and despite yearly fluctuations, overall prevalence increases are apparent in all sex and age classes. Over the past eight years of DNR testing in the core area, prevalence in adult males has risen from about 10 percent to over 12 percent and in adult females from about 4 percent to about six percent. Prevalence in yearling males has increased from about 2 percent to about 4 percent and in yearling females from 2 percent to nearly 6 percent since 2002.

“Simply put, disease prevalence is higher in males than females and higher in adults than yearlings,” said Davin Lopez, DNR’s CWD project leader.

DNR biologists and technicians conducted aerial surveys this winter by helicopter and fixed wing aircraft in the CWD-MZ. The 2009 post hunt population in the CWD-MZ is estimated to be 164,300 compared to 176,300 in 2008 (minus 7 percent), about 185,000 in 2007 and 190,000 in 2006. The total deer harvest in the CWD-MZ in 2009 was 66,013.

DNR biologists know well that after eight years there’s still no easy answer to managing CWD, but they are firm in believing that based on all available evidence, the disease poses a significant threat to the long-term health of Wisconsin’s deer herd and that it is a statewide issue.

“We take our responsibility to manage the disease very seriously in order to try and protect this herd for future generations, the very definition of wildlife conservation. The goal is to minimize the distribution and intensity of CWD.”

“We must take a long-term view of disease management to accomplish this and as we revise our CWD Management Plan, we will again be looking at what this means in terms of different strategies,” added Lopez.

Potential Venison Exposure Among FoodNet Population Survey Respondents, 2006-2007

Belay1 Division of Viral and Rickettsial Diseases, National Center for Zoonotic, Vector-Borne, and Enteric Diseases, Centers for Disease Control and Prevention, Atlanta, GA *Corresponding author e-mail: rmaddox@cdc.gov

The foodborne transmission of bovine spongiform encephalopathy to humans, resulting in variant Creutzfeldt-Jakob disease, indicates that humans can be susceptible to animal prion diseases. However, it is not known whether foodborne exposure to the agent causing chronic wasting disease (CWD) in cervids can cause human disease. The United States Foodborne Diseases Active Surveillance Network (FoodNet) conducts surveillance for foodborne diseases through an extensive survey administered to respondents in selected states. To describe the frequency of deer and elk hunting and venison consumption, five questions were included in the 2006-2007 FoodNet survey. This survey included 17,372 respondents in ten states: California, Colorado, Connecticut, Georgia, Maryland, Minnesota, New Mexico, New York, Oregon, and Tennessee. Of these respondents, 3,220 (18.5%) reported ever hunting deer or elk, with 217 (1.3%) reporting hunting in a CWD-endemic area (northeastern Colorado, southeastern Wyoming, and southwestern Nebraska). Of the 217 CWD-endemic area hunters, 74 (34.1%) were residents of Colorado. Respondents reporting hunting were significantly more likely to be male than female (prevalence ratio: 3.3, 95% confidence interval: 3.1-3.6) and, in general, older respondents were significantly more likely to report hunting than younger respondents. Venison consumption was reported by more than half (67.4%) of the study population, and most venison consumers (94.1%) reported that at least half of their venison came from the wild. However, more than half (59.1%) of the consumers reported eating venison only one to five times in their life or only once or twice a year. These findings indicate that a high percentage of the United States population engages in hunting and/or venison consumption. If CWD continues to spread to more areas across the country, a substantial number of people could potentially be exposed to the infectious agent.

Chronic wasting disease (CWD) of deer and elk is endemic in a tri-corner area of Colorado, Wyoming, and Nebraska, and new foci of CWD have been detected in other parts of the United States. Although detection in some areas may be related to increased surveillance, introduction of CWD due to translocation or natural migration of animals may account for some new foci of infection. Increasing spread of CWD has raised concerns about the potential for increasing human exposure to the CWD agent. The foodborne transmission of bovine spongiform encephalopathy to humans indicates that the species barrier may not completely protect humans from animal prion diseases. Conversion of human prion protein by CWD-associated prions has been demonstrated in an in vitro cell-free experiment, but limited investigations have not identified strong evidence for CWD transmission to humans. More epidemiologic and laboratory studies are needed to monitor the possibility of such transmissions.

The transmission of the prion disease bovine spongiform encephalopathy (BSE) to humans raises concern about chronic wasting disease (CWD), a prion disease of deer and elk. In 7 Colorado counties with high CWD prevalence, 75% of state hunting licenses are issued locally, which suggests that residents consume most regionally harvested game. We used Colorado death certificate data from 1979 through 2001 to evaluate rates of death from the human prion disease Creutzfeldt-Jakob disease (CJD). The relative risk (RR) of CJD for CWD-endemic county residents was not significantly increased (RR 0.81, 95% confidence interval [CI] 0.40-1.63), and the rate of CJD did not increase over time (5-year RR 0.92, 95% CI 0.73-1.16). In Colorado, human prion disease resulting from CWD exposure is rare or nonexistent. However, given uncertainties about the incubation period, exposure, and clinical presentation, the possibility that the CWD agent might cause human disease cannot be eliminated.

CWD Found in Southwestern North Dakota Deer

CWD Found in Southwestern North Dakota Deer

News Release Archives - March 2010 Return to March 2010 Archive

March 17, 2010 CWD Found in Southwestern North Dakota Deer North Dakota Game and Fish Department officials were notified this morning by the U.S. Department of Agriculture’s Veterinary Services that a sick-looking mule deer taken last fall in western Sioux County has tested positive for chronic wasting disease. This is the first time CWD has been detected in a North Dakota animal.

Dr. Dan Grove, Game and Fish Department wildlife veterinarian, said a hunter in unit 3F2 shot an adult buck that did not appear to be healthy. “As we do with our targeted surveillance efforts, we collected the sample to test for CWD and bovine tuberculosis,” Grove said.

The Game and Fish Department’s targeted surveillance program is an ongoing, year-round effort that tests animals found dead or sick.

“We have been constantly monitoring and enhancing our surveillance efforts for CWD because of its presence in bordering states and provinces,” said Greg Link, Game and Fish Department assistant wildlife division chief.

In addition to targeted surveillance, the department annually collects samples taken from hunter-harvested deer in specific regions of the state. In January, more than 3,000 targeted and hunter-harvested samples were sent to a lab in Minnesota. As of today, about two-thirds of the samples have been tested, with the one positive result. The remaining one-third will be tested over the next month.

Link said monitoring efforts have intensified in recent years and all units have been completed twice throughout the entire state.

“The deer population in unit 3F2 is above management goals, and hunter pressure will continue to be put on the population in that unit again this fall,” Link said. “We are going to be aggressive with licenses and disease surveillance in that unit.”

Since the department’s sampling efforts began in 2002, more than 14,000 deer, elk and moose have tested negative for CWD.

CWD affects the nervous system of members of the deer family and is always fatal. Scientists have found no evidence that CWD can be transmitted naturally to humans or livestock.

AS far as human transmission for CWD, you will just have to make your own minds up on that. In my opinion, there is as much evidence for transmission of cwd to humans, as there is for scrapie and BSE to humans. it's the friendly fire there from i.e. cwd exposure that concerns me the most, but the did not recall all this cwd positive elk meat FOR THE WELL BEING OF THE DEAD ELK ;

Potential Venison Exposure Among FoodNet Population Survey Respondents, 2006-2007

Ryan A. Maddox1*, Joseph Y. Abrams1, Robert C. Holman1, Lawrence B. Schonberger1, Ermias D. Belay1 Division of Viral and Rickettsial Diseases, National Center for Zoonotic, Vector-Borne, and Enteric Diseases, Centers for Disease Control and Prevention, Atlanta, GA *Corresponding author e-mail: rmaddox@cdc.gov

The foodborne transmission of bovine spongiform encephalopathy to humans, resulting in variant Creutzfeldt-Jakob disease, indicates that humans can be susceptible to animal prion diseases. However, it is not known whether foodborne exposure to the agent causing chronic wasting disease (CWD) in cervids can cause human disease. The United States Foodborne Diseases Active Surveillance Network (FoodNet) conducts surveillance for foodborne diseases through an extensive survey administered to respondents in selected states. To describe the frequency of deer and elk hunting and venison consumption, five questions were included in the 2006-2007 FoodNet survey. This survey included 17,372 respondents in ten states: California, Colorado, Connecticut, Georgia, Maryland, Minnesota, New Mexico, New York, Oregon, and Tennessee. Of these respondents, 3,220 (18.5%) reported ever hunting deer or elk, with 217 (1.3%) reporting hunting in a CWD-endemic area (northeastern Colorado, southeastern Wyoming, and southwestern Nebraska). Of the 217 CWD-endemic area hunters, 74 (34.1%) were residents of Colorado. Respondents reporting hunting were significantly more likely to be male than female (prevalence ratio: 3.3, 95% confidence interval: 3.1-3.6) and, in general, older respondents were significantly more likely to report hunting than younger respondents. Venison consumption was reported by more than half (67.4%) of the study population, and most venison consumers (94.1%) reported that at least half of their venison came from the wild. However, more than half (59.1%) of the consumers reported eating venison only one to five times in their life or only once or twice a year. These findings indicate that a high percentage of the United States population engages in hunting and/or venison consumption. If CWD continues to spread to more areas across the country, a substantial number of people could potentially be exposed to the infectious agent.

Chronic wasting disease (CWD) of deer and elk is endemic in a tri-corner area of Colorado, Wyoming, and Nebraska, and new foci of CWD have been detected in other parts of the United States. Although detection in some areas may be related to increased surveillance, introduction of CWD due to translocation or natural migration of animals may account for some new foci of infection. Increasing spread of CWD has raised concerns about the potential for increasing human exposure to the CWD agent. The foodborne transmission of bovine spongiform encephalopathy to humans indicates that the species barrier may not completely protect humans from animal prion diseases. Conversion of human prion protein by CWD-associated prions has been demonstrated in an in vitro cell-free experiment, but limited investigations have not identified strong evidence for CWD transmission to humans. More epidemiologic and laboratory studies are needed to monitor the possibility of such transmissions.

Elk tests positive for CWD UTAH

Elk tests positive for CWD


Samples from big game animals taken this past hunting season turned up something never seen in Utah before—an elk with chronic wasting disease.

An elk afflicted with chronic wasting disease.

Photo by Dr. Beth Williams The cow elk—along with five buck deer—tested positive for CWD. The six animals were taken on units in Utah where CWD has been found in past years.

CWD was not found in any new areas in Utah this past fall.

"Chronic wasting disease is most prevalent in deer, but sometimes elk and even moose get it," says Leslie McFarlane, wildlife disease coordinator for the Division of Wildlife Resources.

The cow elk was taken last November on the La Sal Mountains in southeastern Utah. Three of the five deer were also taken on the La Sal Mountains. The two remaining deer were taken on the Central Mountains unit in central Utah.

DWR biologists collected samples from more than 1,100 deer, 37 moose and close to 370 elk this past season.

Since the fall of 2002, the DWR has collected and tested samples from nearly 15,000 mule deer. Of the nearly 15,000 samples, only 48 deer have tested positive for CWD. Thirty-nine of those 48 deer were taken on the La Sal Mountains.

CWD is fatal to deer, elk and moose. But there's no evidence the disease can be transmitted to humans. More information about CWD is available at wildlife.utah.gov/diseases/cwd.

TEN KANSAS DEER CONFIRMED POSITIVE IN CWD TESTS

TEN KANSAS DEER CONFIRMED POSITIVE IN CWD TESTS


Another "presumptive positive" sample still awaiting results


PRATT— On March 2, the Kansas Department of Wildlife and Parks (KDWP) announced that 10 white-tailed deer from northwestern Kansas had tested positive for chronic wasting disease (CWD). These were animals taken by hunters in the 2009 hunting seasons. The agency is still awaiting the result from another deer sample that was presumed to be positive after preliminary testing at the K-State Diagnostic Veterinary Lab in Manhattan. That "presumptive positive" has been sent to the National Veterinary Services Lab in Ames, Iowa, for confirmation.

The one presumptive positive deer was taken by a hunter in Decatur County, and another four deer from that county have been confirmed positive. The other confirmed positives include two from Rawlins County and one each from Sheridan, Graham, Logan, and Thomas counties. One deer each from Sheridan and Thomas counties were exhibiting clinical symptoms of CWD.

In total, 2,702 animals were tested for CWD, including 16 elk, 278 mule deer, and 2,408 white-tailed deer. Although the agency has completed testing of its target sample for this hunting season, biologists are still collecting heads from road-killed deer in northwest Kansas. In addition, the agency is collecting road-killed deer in Harper County, near an area where a captive elk herd had to be destroyed in 2001 because of CWD.

Annual testing is part of ongoing effort by KDWP to monitor the prevalence and spread of CWD. The fatal disease was first detected in a wild deer taken in Cheyenne County in 2005. Three infected deer were taken in Decatur County in 2007 and 10 tested positive in 2008, all in northwest Kansas.

CWD is a member of the group of diseases called transmissible spongiform encephalopathies (TSEs). Other diseases in this group include scrapie in sheep and goats, bovine spongiform encephalopathy (BSE or Mad Cow Disease) in cattle, and Cruetzfeldt-Jacob disease in people. CWD is a progressive, fatal disease that results in small holes developing in the brain, giving it a sponge-like appearance under the microscope. An animal may carry the disease without outward indication but in the later stages, signs may include behavioral changes such as decreased interactions with other animals, listlessness, lowering of the head, weight loss, repetitive walking in set patterns, and a lack of response to humans. Anyone who discovers a sick or suspect deer should contact the nearest KDWP office.

There is no vaccine or other biological method that prevents the spread of CWD. However, there is no evidence that CWD poses a risk to humans or livestock. Still, precautions should be taken. Hunters are advised not to eat meat from animals known to be infected, and common sense precautions are advised when field dressing and processing meat from animals taken in areas where CWD is found. More information on CWD can be found on KDWP’s website, www.kdwp.state.ks.us or at the Chronic Wasting Disease Alliance website, www.cwd-info.org -30-
